From 5eade31eab8b3642d54dbd61934acfeb8bcceb4c Mon Sep 17 00:00:00 2001 From: Oleg Drokin Date: Wed, 24 Feb 2016 22:00:19 -0500 Subject: [PATCH] staging/lustre: Remove server data from struct obd_export Despite it's name struct obd_export could exist on the client too (used for reverse exports), but all the actual server bits are not needed there, so could be dropped. This is mostly various target-related stuff.
